Y GANG CULTIVATOR Application iledf May 6,

ZoH- whomitf concern Befnitz known that; we;f.W1LmaM Ei Hons- Ma-N and: WARRE'N B; `BILLUPs,1 citizens-ot the United States, residingjat: Monticello, in" thefcounty offLewi'sf andi State of Missouritr have inventfedfcertainL new and useful Improvements, in Gang Gultivators, of which. thel followinglis' a'y specification;

This; invention? relates :to gang cult-ivators and?like|` implements', andffhas for one of its objectstovimprovethe construction and increasez thef.efliciency.-` and utility of devices of thisrseharacte'r. Y

Another obj ect'cf ythe-:invention s is to pro.- ducesa device ofi this.1 character including a plunality. of :cultivation teeth',` or shovel carry-ingastandards andwithgmeans for simultaneously adjusting all'of said standards by thenoperation-Qf single shift device.

Anoth'erio'bj ect:.offtlieinvention isz'fto produce device lof =thischaraicter having'- means for.' :individually adjusting thek cultivator teeth carrying standards, and then`x simultaneously adjusting all of thev standards by theioperationofa singlleshifting device.

Wit-litheseandi-other-iobjects in view the invention consists of certain novel features of construction as hereinafter shown and described and then speciiically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a plan view of the improved device.

Fig. 2 is a side elevation.

Fig. 3 is an enlarged sectional detail of the coupling between one of the teeth carrying standards and the supporting frame, on the line 3 3 of Fig. 2.

Fig. 4 is an enlarged plan view of one of the segmentally slotted head members, and

Fi 5 is an enlarged sectional detail on the line 5-5 of Fig. 1.

Fig. 6 is a kdet-ached view of the serrated lock Washer.

The improved device comprises a supporting frame composed of a plurality of bars or beams 10 converged at one end and coupled by a plurality of bolts 11 to a clevis device 12 to which the draft appliance is adapted to be coupled.

At their rear ends two of the beams are offset laterally as shown at 14, and coupled 1921. serial Nar-167,340.

tog. the othergbeams -toiiirmlyv unite kthem-to for-ma-rigidx angular frame, asshownk in Fig. 1,

Attached to.V each ofthe bars 10 atits rear end is a. bearing 15, and snpportedffor rota-tionin eaclrybearing isal standard 16, each ystandard carrying a cultivator tooth or shovel lgatfits lower? end.

. The upper .end of each of the standards 1=6is squarer or of-other fornrv than round, asshown at.' 18, andaslightly tapered, and engagingeachof these .irregular -portilonslis a plate or head member 20 having a'V segmental slot-21 and with a pivotpin-'22 adjustably supported in each slot by afclamp nu'tr 23: Each pivot? pin ha'szfav stopcollar 22l `intermediate 1 the endsV and bearing upon theiupper faceof the'member 20, the lower face. of theicollar 22( 'being serrated to engage corresponding' serrations' 35 in the upper` fa/cel of," the member' 20. By.r this .means the pi-nz 22 1nay be' firmly-'locked in Vthe slot: 21'.- ofl the member 20 to hold the shovel 17l in f adj usted position. j

Each of the' members' 20'is firmlysecu'red to i itsi respective .standardA byf aV clamp nut 24 as shown, and thus rotates with the standards. n

By tapering the upper end 18 of the standard and correspondingly tapering the` hub portion of the member 20, the member v2() may be very tightly coupled to the standard, and in event of the wearing of theparts such wear can be quickly taken up and the tightness maintained by simply' tightening the clamp nut 24, as will be obvious.

Extending over the collar 22 is a shifting bar 25, the latter having openings to loosely receive the upper parts of the pins 22 and secured thereto by clamp nuts 26.

By this means the pins 22 are independently adjustable in the slots 21 to correspondingly adjust the position of the shovels or teeth 17 and then all of the teeth simultaneously adjusted by motion applied 'to the single shifting member 25.

The coacting bearing faces of the members 22 and 25 are correspondingly roughened or corrugated, as represented at 35 and 36 in Figs. 4 and 6, to enable the parts to be firmly clamped together and slipping obviated.

Coupled at its ends at 27 to one pair of the bars 10 is a support 28 having a toothed segment 29 rising therefrom.

Pivoted to the member 28-29 as .indicated at 30 is a shifter lever 31 coupled by a rod 32 to a clip device 33 fast to the bar 25.

A pa-wl device 34 is coupled to the lever 3l and cooperates with the teeth of the segment 29, to hold the lever 3l in adjusted position.

By this simple means the bar 25 may be adjusted to any extent within the range of movement of the lever 31, and thus correspondingly and simultaneously adjust the standards and the teeth or shovels carried thereby.

Previous to the adjustment of the shovel standard by the link bar 25, as above described, the nuts 26 are loosened until the corrugations or teeth 35 and 36 are disconnected, to release the member 25, and then after the adjustments are completed, the nuts 26 are again set up to hold the adjust-- ments.

By this simple means also the shovels or teeth 17 may be independently set to any required extent, and then all the teeth so set simultaneously adjusted to uniformly control their movement through the soil.

The improved device is simple in construction, can be manufactured of metal or partly of metal and partly of wood, and of any required size or capacity.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modification within the scope of the claimed invention may be made in the construction without departingfrom the principle of the invention or sacriiicing an)v of its advantages.

li'vhat Wel claim is l. In a gangcultivator, a supporting,` frame, a plurality of standards rotative in said frame 'and each carrying a cultivator shoveV at the lower end, a head member attached to the upper end of each standard and each formed ivith a segmental slot, an operating rod, coupling devices adjustably connecting said rod respectively with said segmental slots, an operating lever swinging upon said frame, and a link connecting` said lever tosaid operating rod. i

2. In a gang cultivator, a supportingframe, a plurality of standards rotative in said frame, and each carrying ai cultivator shovel at the lower end, ahead member attached to the upper end ofeach standard and each formed with a segmental slot with the material of the head member serrated adjacent the slot, a serrated washer engaging` the serrations of the head member, a pin extending through each of said slots and the adjacent washer, an Operating rod having` spaced apertures to receive said pins, a clamp nut engaging each of said pins and operating to adjustably clamp the rod to the head members, an operating lever swinging upon said frame, and a link connecting said lever to said operating rod.

In testimony whereof we affix our signatures hereto.
